Thanks for your reply. I have also been increasingly dissatisfied with
Universal Strings. However, even ordering specific strings often pose
troubled matches I've noticed lately. If I receive one more poorly matched
string, I'm going to order both bichords...
Anyway, I should also have known that since 2 complete notes were out, there
would be no chance of replacing with Universals, since I need 2 pairs. These
were indeed copperwound, and I'm afraid since they're at the break that the
tension may be a bit high. I will ask the stringmaker if he can do something
about that. I did not measure the adjacent strings.
